Debian DLA-1076-1 : php5 security update

High Nessus Plugin ID 102843

Synopsis

The remote Debian host is missing a security update.

Description

The finish_nested_data function in ext/standard/var_unserializer.re in PHP is prone to a buffer over-read while unserializing untrusted data.
Exploitation of this issue can have an unspecified impact on the integrity of PHP.

For Debian 7 'Wheezy', these problems have been fixed in version 5.4.45-0+deb7u11.

We recommend that you upgrade your php5 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
